FLUSHING APPARATUS.

SECIFICATION forming part of Letters Patent No. 790,796, dated May 23,1905.

Application filed February 20, 1904. Serial No. 194,463.

To all 7,071,077?, 7175 nea/y concern:

Be it known that I, CHARLES WV. LENDH, of Brockton, in the county ofPlymouth and State of Massachusetts, have invented certain new landuseful Improvements in Flushing Apparatus, of which the following is aspecification.

This invention relates to flushing apparatus comprising a reservoirhaving an outlet at its bottom portion surrounded by a valve-seat and aninlet above the valve-seat communicating with a source of water-supply,a Valve in the reservoir normally closed on the valveseat to cause theaccumulation of a iushing charge of water in the reservoir, and meansfor opening the valve to permit the escape of said charge through theoutlet.

The invention has for its object to provide a simple, compact, andeffective {iushing apparatus of this class adapted to bc manufacturedand installed at a minimum expense.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specification,Figure l represents a vertical central section of a iushing apparatusembodying my invention. Fig. 2 represents a section on line 2 2 ofFig. 1. Fig. 3 represents an elevation looking toward another side ofthe apparatus.

The same reference characters indicate the same parts in all theligures.

In the drawings, a` represents a reservoir, which is closed at its upperportion and has an outlet branch 77', extending downwardly from itsbottom, said branch being tubular and surrounding a valve-seat 6, whichin turn surrounds the outlet of the reservoir.

t2 represents an inlet branch located below the top of the reservoir andabove the outletA branch and valve-seat. The inlet branch may beconnected in any suitable way with a pipe communicating with a source ofwater-supply.

c represents a flush-pipe section forming a continuation of the passagethrough the outlet branch'a'. The valve-seat b is formed on a tubularbushing which is formed to be removably inserted in the outlet branch aand has a peripheral flange If between its upper and lower ends. Thelower portion ofY the bushing is preferably somewhat contracted at b3and is provided with an external screw-thread, which is engaged with aninternal thread formed in the upper end of the section c.

CZ represents a coupling-nut, which is internall y thread ed to engagean external thread 0n the outlet branch c and has a shoulder (Z, whichengages the flange of the bushing 2). It will be seen, therefore, thatthe bushing and the flush-pipe section are detachably connected by thenut (Z with the outlet branch c, so that the reservoir may be separatedfrom the bushing andthe Hush-pipe section, the bushing being separablefrom the flush-pipe c. The valveseat is formed on the upper end of thebushing b, and hence it is exposed when the parts are separated.

represents a valve. which is normally closed upon the valve-seat Z7 toconfine the body of water in the reservoir c. The valve is provided witha stem which extends downwardly to a guide 2 in the bushing L andthrough a stufing-box which is engaged with an oifset portion c2 of thesection c. The valve-stem projects below and outside of the offsetportion c2 and is engaged at its lower end with a lifting device, whichis preferably a lever j, fulcrumed at j to a fixed support, which isattached to the section c, as shown in Fig. 3, one arm of said leverbeing engaged with an arm i" on the lower end of the valvestem cf.

7c represents a spring which is interposed between the valve-stem guide2 and a shoulder 5 upon the valve-stem, said spring normally holding thevalve against its seat.

As shown in Fig. 3, the arm c* of the valvestem z' is provided with anose or downward projection i, which bears on the lever j' at a pointmuch nearer the fulcrum of said lever han the forked end of the arm 4.These parts are in practice so proportioned that when the valve isfirmly seated the only part of the arm c'* which bears on the lever isthe projection 6. When the lever is moved to raise the valve-stem andvalve, the lever acts lirst on the nose-i, which is relatively close tothe fulcrum of the lever, so that the lever acts through a relativelyshort arm in the initial raising o1 the valve from its seat when theresistance to the upward movement of the valve is the greatest. As theshorter arm of lever y'swings upwardly it strikes the outer portion ofthe arm 4 after the valve has been raised from its seat and imparts anadditional and more rapid upward movement to the valve. The valve t' isso formed that .when the reservoir and the section c are disconnectedthe valve can pass freely through the outlet branch a. Provision is thusmade for readily obtaining access to the valve and its seat. Theapparatus is supported by means of ears m m, formed on the flush-pipesection c, said ears being attached by screws to a wall or other supportand oset from the reservoir, as shown in Fig. l, so that the reservoiris out of contact with the wall, the outer Jface of said ears being in aplane laterally beyond or at one side of the vertical plane of the rearside of the reservoir. Therefore the reservoir and then the valve, nut,and valve-seat may be removed without detaching the rest of the devicefrom the wall or other support.

It will be seen that the entire Vapparatus is of compact and simpleconstruction, the valveoperating mechanism being located at the lowerportion of the apparatus and imposing no strain upon the reservoir whichis not required to support any of the operative parts. The describedprovisions for permitting the removal of the valve-seat and valve enablethe apparatus to be readily kept in good working Order. The ofsetportion 020i' the flush-pipe section and the stufHng-box 3 thereinenable the valve to be operated by a stem arranged in the line ofmovement of the valve, the valve-operating mechanism as a whole beingrelatively simple and inexpensive.

The apparatus may be readily installed in the desired position byscrewingtheears m m to a wall, and when so installed the reservoir maybe disconnected without disturbing the Hush-pipe Aby'unscrewing the nutcl. lhe removal of the reservoir exposes the valve-seat and valve, thereservoir being adapted to be lifted from the valve-seat and valve. Thearm c", laterally extended from the valve-stem, enables the lever 7' tobe fulcrumed at a point in close proximity to the valve-stem, as shownin Fig. 3.

I claim- 1. A iiushing apparatus comprising a reservoir having an outletat its bottom portion, a valve for controlling said outlet and havingits stem extending downwardly therefrom, the lower end of said stemhaving a downward projection or nose in the axial line of the stem, anarm extending laterally therefrom, and a lifting-lever having one endextending under the said nose or projection of the valve-stem and havingan operative connection with the outer end of the lateral arm of saidvalvestem, whereby the lever may initially raise the valve by contactwith said nose or projection.

2. A flushing apparatus comprising a reservoir having an outlet at itsbottom portion surround ed by a valve-seat, and an inlet above thevalve-seat communicating with a source of water-supply, a flush-pipesection connected with the outlet and having an offset portion below theoutlet, one wall of said portion having a stuiing-box, a valve in thereservoir formed to close on said valve-seat, a stem axed to the valveand extending downwardly through said stuffing-box, said stem having alaterally-extending arm at its lower portion and having also a downwardprojection or nose in the axial line of the stem, and a lifting-leverfulcrumed to asupport attached to the Hush-pipe section and engaged withthe said arm, said lever supporting the said nose or projection near thefulcrum of the lever.

3. A flushing apparatus comprising a reservoir having anexternally-threaded tubular outlet branch extending downwardly from itsbottom and an inlet above the bottom, a tubular bushing having avalve-seat at its upper end and removably inserted in said branch, saidbushing having an external peripheral flange seated on the lower end ofthe outlet branch, and an externally-threaded portion below the iiange,a Hush-pipe section internally threaded to engage the external thread ofthe bushing, a coupling-nut engaging the external thread of the outletbranch and the flange of the bushing to detachably secure the flush-pipesection and the bushing to the outlet branch. a valve within thereservoir normally closed on said valve-seat, and means for opening thevalve, the diameter' of the valve being less than that of the outletbranch.

In testimony whereof I have aixed my signature in presence of twowitnesses.
